Overview
The PS2561DL2-1Y-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a DIP-4 Gull Wing surface-mount package. The device provides 5000 Vrms isolation voltage between input and output. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.4 V at a maximum forward current of 40 mA. The typical rise time is 3 µs and the fall time is 5 µs.
Feature Summary
- Provides high-voltage electrical isolation for signal transmission
- Utilizes an NPN phototransistor for digital switching applications
- Designed for surface-mount assembly in compact form factors
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing between microcontrollers and power circuits
- Solid-state relay driver circuits
Procurement Notes
Verify the exact suffix 'L-A' against official Renesas documentation to confirm lead time and availability status, as suffixes often dictate specific packaging or regional compliance variations. Ensure the component matches the required DIP-4 Gull Wing footprint and thermal specifications for the target PCB design before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount solution with 5000 Vrms isolation is required for single-channel DC signal coupling. Compare the 40 mA forward current limit and 80 V collector voltage against system requirements. Verify that the 3 µs/5 µs switching speeds meet the application's timing constraints compared to through-hole alternatives.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers from Renesas Electronics. The series includes various packages such as DIP-4 and SMD configurations. The DL2 variant specifically denotes the surface-mount gull-wing package style, distinguishing it from standard through-hole DIP versions within the same functional family.
